HOLDER FOR BOOT AND SHOE FORMS.

Specicaton of Letters Patent.

Patented Nov. 30, 1909.

To all 'whom it may concern:

Be it known that I, VTHOMAS F. MCGANN, of Somerville, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Holders for Boot and Shoe Forms, of which thefollowing is a specication.

Thisl invention relates to a new and irnproved holder for boot or shoeforms and consists in the novel features of construction and relativearrangements of parts hereinafter fully described in the specification,clearly illustrated in the drawings and particularly pointed out in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis application wherein like characters are used to indicate like partswherever they occur.

Figure l is a perspective view showing an apparatus constructed inaccordance with my invention. Fig. 2 is an end view of the apparatusshown in Fig. l, showing dierent adjustments of the shoe form. Fig. 3 isa vertical sectional view on the line 3-3 of Fig. 2 looking in thedirection of the arrow. Fig. a is a cross sectional view on the line 4 4of Fig. 3 showing the split clamp and the method of its engagement withthe arm. Fig. 5 is a cross sectional View on the line 5 5 of Fig. 3showing the engagementof the expansion shell with the socket carried bythe heel of the shoe form. Fig. 6 is a detailed view showing thearrangement of the expansion shell, expansion spindle and its plug.

l represents the heel part of a shoe form. rlhe forepart as shown iscomposed of two members 2 2 connected to the heel part l by a pintle 2a.Springs 2b serve to yieldingly separate the members 2 2 to lill andsupport a shoe-upper. Such shoe forms are known as split followers andrequire no further description. Any other' preferred kind of shoe formmay be employed, the purpose being to employ a form of suitableconstruction upon which a shoe may be readily placed and easilywithdrawn.

3 represents a socket arranged in a complemental recess in the heel partand secured in place by a screw 4e.

5 represents a bracket adapted to be secured by screws 6 to an uprightor any other preferred supports. This bracket carries a hollow sleeve 7.This sleeve 7 at its free end is slotted as at S and carries 0r isformed integral with a slotted clamp 9, having ears l0 l0.

l1 represents a clamp screw arranged in ears l0, by which the clamp 9and the slotted end of the sleeve 7 may be contracted or expanded.

lhe arm of the apparatus comprises a ball 20 carrying upon one side aspindle 21 adapted to be arranged in the sleeve 7 and locked in place bythe clamp screw 1l.

22 represents a stem here shown in the form of an expansible cylindricalshell carried by the ball 20. The lower end of this shell is slotted asat 2l represents an expansion spindle arranged in the shell 22. Thisspindle at its lower end carries an expansion plug 25 that projectsbelow the lower end of the spindle, in order to engage the split end ofthe shell and expand it against the wall of the socket 3. if desired theshell near the upper end of the slot 23 may be formed with an incline 27adapted to be engaged by complemental incline 2S on the spindle 24 inOrder to expand the shell at the upper part of said slot. It will beseen that the incline 28 and the inclined plug 25 cooperate to expandthe shell 22 in the form socket by movement of its sides insubstantially parallel lines.

This feature is of advantage in holding the form firmly upon the shell.

29 represents a spring arranged about the spindle 24: and engaging atone end a shoulder on said spindle and at its opposite end engaging aseat in or carried by the ball 22, and arranged to normally throw theexpansion plug 25 and the incline 28 downward or outward to release theexpansion shell and permit its contraction.

30 represents a nut, arranged upon the threaded upper end of the spindle24 and bearing against the ball 20. By means of this nut which may beprovided with a handle, as shown, the expansion plug 25 and the incline28 can be made to expand the shell against the socket 3 and lock theshoe form rigidly in place.

The operation of my improved apparatus is as :tolloWs:-The parts beingconstruct-cd and arranged as described and positioned as desired, a shoeis drawn upon the shoe form, t-he latter supporting and filling out theupper. The shoe is then cleaned and polished or subjected to any desiredoperation after Which the shoe is Withdrawn from the form, the parts 2 2of the latter yielding to permit the ready passage of the form throughthe Waist of the shoe Without injury to the latter, either in theoperation or" placing the shoe on the form or removing the shoe from theform. By means of the clamp 9, the shell may be moved to and locked inany desired position of adjustment (see for illustration the dotted lineposition of parts in Fig. 2) by turning the spindle 21 in the sleeve 7and clamp 9. The radial position of the shoe with respect to the axis oft-he shell 22 may be varied as desired by turning the form about the endof said shell and then locking the form to the shell. The form isfrictionally held upon the shell 22 and may be held thereon with anydesired degree of firmness by adjusting the nut 30. This constructionmay be used to advantage in operating upon a shoe sustained upon theform, since it permits the resistance to pivotal movement of the formupon said shell to be varied as desired.

Having thus explained the nature of my invention, and described a Way ofconstructing and using' the same, although 'Without attempting to setforth all the forms in which it may be made, or all of the modes of itsuse, I declare that What I claim is l. In an apparatus of the classspecified, a support, an arm carried by said support, a clamp forrigidly securing the said arm to said support, a shell carried by saidarm, slotted at its tree end and adapted to rece-ive upon said free endthe socket of a shoe form and to permit pivotal movement of said form onsaid slotted end, a spindle arranged in said shell and provided Withmeans for expanding the free end of said shell, Whereby said form may berigidly locked in any desired position of adjustment about said shell.

2. In an apparatus of the class described, a support, an arm carried bysaid support and adapted to be adjusted about said support as an axis, ashell carried by said arm slotted at its free end and arranged in aplane substantially perpendicular to the axis of said arm, a spindlearranged in said shell and provided with a member lt'or expanding theslotted end of said shell and means to force positively said spindlelongitudinally of the shell to expand said slotted end.

3. In an apparatus of the character speciiied, a socket-member carriedby the heel of ashoe form, a shell arranged to be inserted therein andadapted to permit pivotal movemovement of the form on the shell, an armformed with an expanding member arranged in said shell to Vexpand thelatter against said socket member, means for supporting the said armadapted to permit its adjustment around said means as a center and meansfor clamping the arm in adjusted position.

4. In an apparatus of the class speciiied, a support, an expansibleshell sustained thereby and adapted to be inserted in the pin hole or' ashoe form or last, a spindle, and means to move said spindlelongitudinally in said shell, the spindle being provided with inclinedfaces located at successive points longitudinally of said spindlearranged to engage the interior face of the shell whereby the shell Willbe expanded by movement of its sides in substantially parallel lines.

5. A holder for a shoe form or the like, comprising a support, a stemadjustably clamped in stationary position upon said support andconstructed to enter a socket in the form and to support said formpivotally, and means extending Within the stem for locking said formupon said stem.

A, holder for a shoe Jform or the like comprising a support, atubular expansible stem carried by said support constructed to enter asocket in the form and to support said form pivotally, and means forexpanding said stem by engagement With its inner surface to hold saidform frictionally in position.

7. A holder for a shoe form or the like, comprising a support, anexpansible stem carried by said support constructed to enter a socket inthe form and to support said form pivotally, and means for expandingsaid stem at a plurality of successive points longitudinally thereof tohold said form upon the stem.

8. A holder for a shoe form, having in combination, a stem constructedto enter a socket in the form and to support the form pivotally, ahorizontal support for sustaining the stem having provision forpermitting adjustment of the form in the direction of the length of thesupport and for permitting its adjustment about an axis parallel Withthe support and means extending Within the stem for locking said formupon said stem.
